Endocytosis is a cool process that helps cells take in big molecules that can’t just squeeze through the cell's outer layer. Here’s how it happens:
Membrane Invagination: The outside of the cell starts to fold in on itself, making a tiny pocket that wraps around the big molecule, like proteins or even whole bacteria.
Vesicle Formation: This little pocket then pinches off from the cell’s surface to create a vesicle. This vesicle carries the big molecule inside the cell.
Types of Endocytosis:
With endocytosis, cells can collect the nutrients or materials they need, just like using a scoop to gather food. It’s super important for immune cells, helping them to swallow up and get rid of harmful germs!
